3,716 Points"Implementation of Description" not being accepted as correct, why not?
struct Tag { let name: String }
struct Post { let title: String let author: String let tag: Tag
func description() -> String { let descriptionString = "(title) by (author). Filed under (tag.name)." return descriptionString } }
let firstPost = Post(title:"iOSDevelopment", author:"Apple",tag:Tag(name:"Swift"))
let postDescription = firstPost.description()
// THERE IS NOTHING TO CHECK IN THE OUTPUT, I'VE NO FEEDBACK. // It mentions to use string interpolation. I am doing so. I also tried the following: // return "(title) by (author). Filed under (tag.name)." //this fails as well.
struct Tag {
let name: String
}
struct Post {
let title: String
let author: String
let tag: Tag
func description() -> String {
let descriptionString = "\(title) by \(author). Filed under \(tag.name)."
return descriptionString
}
}
let firstPost = Post(title:"iOSDevelopment", author:"Apple",tag:Tag(name:"Swift"))
let postDescription = firstPost.description()

6,443 PointsFirst, there's no dot at the end of the sentence you are supposed to return.
Second, you have to return that sentence, not a constant/variable. So, not this: let something = "AAAAA" return something But this: return "AAAAA"

3,716 PointsThanks for answering. I figured it out soon after posting but don't know how to retract a post.
The extra "." was the problem. Returning a constant with the string is OK, although I initially started with just returning a string, I changed it when I couldn't figure out what the problem was.
